Abstract:
L'invention concerne un substrat comprenant deux faces principales définissant deux surfaces principales séparées par des bords, ledit substrat portant un revêtement fonctionnel déposé sur au moins une partie d'une surface principale et une couche de protection temporaire déposée sur au moins une partie du revêtement fonctionne. La couche de protection temporaire,durcie par séchage, par irradiation UV ou par faisceau d'électrons, a une épaisseur d'au moins 1 micromètre et est non soluble dans l'eau. Cette couche de protection temporaire est obtenue à partir d'une composition liquide comprenant des composés (méth)acrylates choisis parmi des monomères, des oligomères, des prépolymères ou des polymères comprenant au moins une fonction (méth)acrylate.
Abstract:
The present invention provides a chemically toughened ultrathin glass, said glass has a thickness less than 500 μm, a surface compressive layer having a depth of at most 30 μm. Said toughened ultrathin glass sheet is more flexible and has extraordinary thermal shock resistance with the glass being easier to handle for processing.
Abstract:
Laminated structures comprise a metal sheet including a first face and a second face with a thickness of from about 0.5 mm to about 2 mm extending between the first face and the second face. The laminated structure further includes a first chemically strengthened glass sheet including a thickness of less than or equal to about 1.1 mm and a first interlayer attaching the first chemically strengthened glass sheet to the first face of the metal sheet. In further examples, methods of manufacturing a laminated structure comprise the steps of laminating with a metal sheet and a first chemically strengthened glass sheet together with an interlayer.
Abstract:
A method of making glass through a glass ribbon forming process in which a glass ribbon is drawn from a root point to an exit point is provided. The method comprises the steps of: (I) cooling the glass ribbon at a first cooling rate from an initial temperature to a process start temperature, the initial temperature corresponding to a temperature at the root point; (II) cooling the glass ribbon at a second cooling rate from the process start temperature to a process end temperature; and (III) cooling the glass ribbon at a third cooling rate from the process end temperature to an exit temperature, the exit temperature corresponding to a temperature at the exit point, wherein an average of the second cooling rate is lower than an average of the first cooling rate and an average of the third cooling rate.
Abstract:
A thin lightweight glass fascia for appliances. The fascia may be a seamless shaped glass fascia for an appliance, such as a glass fascia that wraps around at least two opposing edges of an appliance. The glass fascia may seamlessly incorporate a display or control panel under the fascia. A mounting arrangement that facilitates quick fascia removal and replacement may be provided. The fascia may be a chemically-strengthened glass sheet having a thickness of less than 2.0 mm, and a near-surface region under a compressive stress, wherein the compressive stress (CS) at a surface of the first glass sheet is greater than 300 MPa and extends to a depth of layer of at least 20 micrometers.
Abstract:
The invention relates to lithium aluminosilicate glass and to a method for the production of lithium aluminosilicate glass, the glass having the following composition (in mol%): 60 - 70 SiO2; 10 - 13 Al2O3; 0.0 - 0.9 B2O3;9.6 - 11.6 Li2O; 8.2 - 2O; 0.0 - 0.7 K2O; 0.0 - 0.2 MgO; 0.2 - 2.3 CaO; 0.0 - 0.4 ZnO; 1.3 - 2.6 ZrO2; 0.0 - 0.5 P2O5; 0.003 - 0.100 Fe2O3; 0.0 - 0.3 SnO2; 0.004 - 0.200 CeO2.
